I'm watching youtubers play this like Fooster and looking at screenshots and I've noticed floors starting at 42F and below have no map? I plan to get this but I'm wondering If each floor has some map you need to find?

Made it all the way to B2 and realised I have literally no idea what the aim of the game is. I thought you were trying to make it to the ground floor to escape? I tried looking for a guide but they're all in Chinese or something. Could someone point me to an objective or goal of some kind?...

make a save option with unspawnable material is crazy because you loose so much material just for a safe (and in my cause want i wanted load, i must start over , so cannot trust, + not know if you have enough material to play game , if all go to just saving......................

So only have a little over 2 hours so not the worst if I have to reset, but still not great. I was down quiet a few floors, found a second map and 2 keycards so made decent progress. I saved the game then exited via menu. Now the save will not load, gets to about 10 or 11/16 on the loading progress and crash to desktop. Not sure what causes it and it has no crash/error log to pop up so got nothing to post here...

i started a new game and my char keeps spinning in the spot if i turn the mouse sensitivity to 0 it stops but the mouse dose not work then but if mouse sensitivity increased the char starts to spin again.
